  • Digital Object Identifiers: Affecting How Libraries Connect to Online Digital Content

    1. 1. Digital Object Identifiers: Richard Bernier Reference & Electronic Services Librarian April 13, 2004 Affecting how libraries connect to online digital content
    2. 2. What is DOI? <ul><li>An identification system for intellectual property in the digital environment </li></ul><ul><li>Developed by the DOI foundation on behalf behalf of the publishing industry to provide a framework for managing intellectual content, link customers with publishers, facilitate electronic commerce, and enable automated copyright management. </li></ul>
    3. 3. But what does it really do? <ul><li>A persistent identification number assigned to a unit of content and registered with a lookup service. </li></ul><ul><li>Not only an identifier of digital objects, but also a digital identifier of objects. </li></ul><ul><ul><li>e.g non-digital entities, such as underlying abstractions (the “work”) and physical manifestations. </li></ul></ul>
    4. 4. Implementations <ul><li>Journals or single journal articles </li></ul><ul><li>Books or book chapters </li></ul><ul><li>Entire opera or single bar of music. </li></ul><ul><li>Digitized or non-digitized audio, video, images, text </li></ul><ul><li>An article is Spanish and in English could have one DOI for both, or separate DOIs for each language </li></ul>
    5. 5. International DOI Foundation (IDF) <ul><li>DOI organization established to develop and manage the DOI system </li></ul><ul><li>Launched in 1998 by the Association of American Publishers, International Publishers Association, and the International Association of Scientific Technical and Medical Publishers </li></ul>
    6. 6. DOI Basics <ul><li>Single resolution: DOI points to 1 URL </li></ul><ul><li>Multiple Resolution: DOI points to multiple URLs (e.g. Full text, purchase option, abstract) </li></ul>DOI> 10.1000/1234 URL DOI> 10.1000/1234 URL 1 URL 2 Data 1 Data 2 Example
    7. 7. DOI Basics <ul><li>DOI System made up of four parts </li></ul><ul><ul><li>The identifier (Numbering scheme) </li></ul></ul><ul><ul><li>Resolution </li></ul></ul><ul><ul><li>Metadata </li></ul></ul><ul><ul><li>Policy </li></ul></ul>
    8. 8. Identifier <ul><li>The identifier is made up of two components – the prefix and the suffix. </li></ul><ul><ul><li>While the URL to the object may change, the DOI identifier does not. </li></ul></ul>Prefix Suffix DOI <ul><li>Prefix represents the </li></ul><ul><li>publisher of registrant </li></ul><ul><li>Suffix is unique to that object. Can be already used number like an ISBN #. </li></ul>
    9. 10. Resolution <ul><li>Ensures persistence by resolving the DOI to a current associated value such as a URL; </li></ul><ul><li>Resolution may be to multiple pieces of data (multiple resolution); </li></ul><ul><li>The Handle System is the resolution system used. </li></ul>
    10. 11. Registration Agencies <ul><li>Provide Services to Registrants </li></ul><ul><li>Allocate DOI prefixes </li></ul><ul><li>Registering DOIs and providing the necessary infrastructure to allow Registrants to declare and maintain metadata and state data. </li></ul>
    11. 12. Registration Agencies <ul><li>Content Directions </li></ul><ul><li>Copyright Agency, Ltd. </li></ul><ul><li>CrossRef </li></ul><ul><li>Enpia Systems </li></ul><ul><li>Lon, Inc. </li></ul><ul><li>mEDRA </li></ul><ul><li>Nielson BookData </li></ul><ul><li>R.R Bowker </li></ul><ul><li>TSO (The Stationary Office </li></ul>
    12. 13. Metadata <ul><li>Each DOI has attached metadata set which describes it. </li></ul><ul><li>Standard metadata includes: </li></ul><ul><ul><li>What is the resource that is identified? </li></ul></ul><ul><ul><li>Does it have another identifier that can be recognized (e.g. an ISBN)? </li></ul></ul><ul><ul><li>Who are the parties responsible for its creation? </li></ul></ul><ul><ul><li>What is it made of? (abstract, physical, digital) </li></ul></ul><ul><ul><li>How is it perceived? (visual, audio, etc) </li></ul></ul><ul><ul><li>Particular application type? (e.g article linking)? </li></ul></ul>
    13. 14. Policy <ul><li>Rules determined by the International DOI Foundation for the operation of the DOI System in a consistent, predictable, and controlled manner to ensure longevity of the system as infrastructure. </li></ul><ul><li>Use of Registration agencies which operate under same rules as an operational federation. </li></ul>
    14. 15. DOI Diagram Norman Paskin, Digital Object Identifier: Overview , Administrator ( Identifier: DOI: 10.XXXX/1234 URL: Title: New Horizona - Latin Jazz Agent = Author: John Jakob-Jemènez Type: digital file Mode: Text: 250 pages Images: 20 Moving Images: 2 Audio: 20 Release Date: January 1, 2001 Rights Profile: Translation Paperback Electronic Email Contact: [email_address] Other Titles by Author: Title 2 ; Title 3 Retailers: amazon ; bol ; DOI data and metadata (XMLbatch) DOI data and metadata Registration Agency Metadata Collection metadata DOI System DOI data
    15. 16. Progress of Project <ul><li>August 2003: 10 millionth DOI was assigned via CrossRef </li></ul><ul><li>Over 300 professional publishing organizations joined up. </li></ul><ul><li>9 Registration Agencies </li></ul><ul><li>6 Charter Members & 17 General Members that fund & support the foundation and develop the system </li></ul>
    16. 17. Benefits of the DOI system to libraries <ul><li>Persistence, persistence, persistence!!! </li></ul><ul><li>Successful implementation of naming objects & treating content as information objects and intellectual content, not simply as packets of bits. </li></ul><ul><li>DOIs are easy to use. Simply click one or cut and paste it like you would a URL. </li></ul>
    17. 18. Benefits of the DOI system to libraries <ul><li>Called the “barcode for intellectual property” – access to content is similar to shopping. </li></ul><ul><li>Multiple resolution capability leads to more options for researchers. </li></ul>
    18. 20. CrossRef Indicators As of March 24 th 2004 <ul><li>299 participating publishers </li></ul><ul><li>278 participating libraries </li></ul><ul><li>9,474 journals covered </li></ul><ul><li>10,497,910 DOIs registered </li></ul><ul><li>204,823 DOIs deposited in previous month </li></ul><ul><li>4,996,005 DOI resolutions (end-user clicks) in previous month </li></ul>
    19. 28. 10.1016/j.jneuroling.2003.10.001
    20. 30. Resolve a DOI <ul><li>Go to & enter DOI </li></ul>
    21. 32. Look up an article’s DOI
    22. 34. DOI and OpenURL standard <ul><li>OpenURL is a standard syntax that provides a universal way to define citation information as a URL. </li></ul><ul><li>Metadata is passed to a link resolver via URL which determines a user’s content access permissions and directs them to the appropriate copy. </li></ul><ul><li>SFX and EBSCO’s LinkSource are link resolvers. </li></ul>
    23. 35. DOIs on the other hand… <ul><li>Do not resolve appropriate copy issue alone. </li></ul><ul><li>Are persistent and facilitate access to full text options, articles referenced, and times cited references. </li></ul>
    24. 36. Library without Link Server Citations with DOI link DOI> DOI Server Abstract Full Text PDF Buy Article URL
    25. 37. How DOIs and OpenURL work together DOI> DOI Server OpenURL Server Citations with DOI link SFX Result Box
    26. 38. What to expect in the future? (for librarians) <ul><li>Forward linking (cited by) in addition to reference linking </li></ul><ul><li>More entity linking (e.g. charts, images, diagrams, etc within journal articles, books, & other works) </li></ul><ul><li>Increase in multiple resolution applications </li></ul>
